FormatTextとIso_2022_jp_mail

こちらのサイトで公開されているPlaggerのプラグイン。
フィードを携帯とかに送りたい時、PlainTextのメールで欲しいとかMIMEがmixedなのは嫌だって時に便利な以下の二つのプラグインだが、上手く動かなかったりスペル間違いがあったりしたので自分なりにがんばって修正してみた。

Filter::FormatText

package Plagger::Plugin::Filter::FormatText;
use strict;
use base qw( Plagger::Plugin );

use HTML::TreeBuilder;
use HTML::FormatText;
use Encode;

sub register {
    my($self, $context) = @_;
    $context->register_hook(
        $self,
        'update.entry.fixup' => &filter,
    );
}

sub filter {
     my($self, $context, $args) = @_;
     my $cfg   = $self->conf;
     my $entry = $args->{entry};

     my $left  = $cfg->{left_margin}  || 0;
     my $right = $cfg->{right_margin} || 72;
     my $tree      = HTML::TreeBuilder->new()->parse($entry->body);
     my $formatter = HTML::FormatText->new(
         leftmargin => $left,
         rightmargin => $right,
     );
     my $body = $formatter->format($tree);
     my $len  = length($body);

     my $start = $cfg->{start}  || 0;
     my $end   = $cfg->{length} || $len;

     if ($cfg->{start} || $cfg->{length}) {
       my $more = '';
          $more = ' ...' if $len > $end;
       $body = substr($body, $start, $end) . $more;
     }
#     $entry->body('</pre><pre>'.$body.'</pre>');
     $entry->body($body);

     $context->log(info => "format $entry->{link}") if $entry->{link};
}
